AI Tools for Fundraising Consultants: ChatGPT, Claude or a Platform?

For most fundraising consultancies, a $17 to $20 ChatGPT or Claude plan already handles appeal drafts, thank-you letters and first-draft proposals. A platform earns its fee only for jobs a chat assistant cannot do: live funder databases, prospect research and donor records. Grantable's paid plans start at $50 a month and Instrumentl's at $299 on annual billing.

The claim is easy to test on your own past work. Run five recent jobs through an assistant and one platform, log the editing minutes, and buy the platform only if the hours it saves, at your hourly rate, beat its fee. At $75 an hour, Instrumentl's $299 has to save four hours a month before it pays.

Which jobs a $20 assistant already does

Split the work by what the job needs. Writing from material you supply is what general assistants do well. Anything that needs fresh facts about funders or private facts about people is where they fail or where a platform's data matters.

Read down the second column and a pattern appears. Of eight jobs, five are writing or analysing material you hand over, and an assistant is enough. Two (funder research and prospect screening) depend on data the assistant does not hold. One (segmentation) can go either way depending on where the records live. For broader context on which jobs a consultant can sell, see five jobs a consultant can offer clients.

What each route costs a month

All prices are USD list prices from vendor pages in October and November 2026, with annual billing quoted where a vendor shows it.

Grantable's page lists every plan with the same features, with the difference being capacity: Free allows 5 chat messages a day, Starter 50 and Pro 200, and there are no per-seat fees. An Agency Hub add-on is $300 a month. Instrumentl's Pre-Award plan describes an "Apply" feature that uses AI plus your past content to write faster, while the Discover plan lists a beta AI prospecting assistant. Both are as the pricing pages showed when I fetched them, so check them before you budget.

Three stacks follow from those prices.

• Assistant only: $17 to $20 for one consultant, $40 to $50 on a business plan.
• Assistant plus Grantable Starter: about $67 to $70, which adds a place to store past proposals and run them through a grant-focused writing tool.
• Assistant plus Instrumentl Discover: about $316 to $319, which adds funder research, and is the first step that needs a serious justification.

A discount that probably is not yours

OpenAI lists ChatGPT Business Standard seats at $8 a user a month on annual billing ($10 monthly) for nonprofits, and Anthropic lists Claude Team at $8 a seat with a two-seat minimum. Those discounts are for eligible nonprofit organisations, which your clients may be and your consultancy probably is not. It still matters: if you set up an assistant inside a client's own account, their price may be a fraction of yours. The wider list of claimable offers is in AI tool discounts for charities and non-profits.

Where chat assistants let a fundraising consultant down

Four failures are worth knowing before the trial, because the trial should try to provoke each.

Invented funders. Ask an assistant for foundations that fund youth literacy and you may get a tidy list in which one funder does not exist and another stopped giving in that area years ago. Treat every name as a lead, and confirm it on the funder's own site and in its published grant lists. This is the job where a maintained database earns its fee, though databases go stale too.

Invented impact. Asked for an appeal letter, an assistant will happily write "90 per cent of our children read at age level". If your fact sheet did not say that, it made it up. The fix is in the prompt below.

Wrong deadlines and eligibility. Assistants misread or misremember application windows. Always copy the deadline from the funder's page into your tracker by hand.

Private data. An assistant has no access to wealth data and should not guess at it. A consultant who asks one to "estimate this donor's capacity" is asking it to invent a number about a real person.

A ten-day trial that settles it

The trial compares results on your own work rather than feature lists, and it fits around client work over two working weeks.

1. Pick five jobs from your last quarter: for example an appeal letter, a thank-you letter, a case for support, a grant section and a funder shortlist.
2. Prepare the inputs once. For each job, a one-page fact sheet of real, approved numbers and quotes, plus one past example in your preferred voice. Remove donor and staff names.
3. Run each job through each tool. At minimum ChatGPT Plus and Claude Pro on their trials or free plans, and one platform on a free tier or demo. Use identical instructions, and save each output unlabelled.
4. Score blind. Ask a colleague, or yourself the next day, to score each output from 1 to 5 on four criteria: accuracy to the fact sheet, voice, editing time needed, and risk if sent as is.
5. Log minutes. Record how long each job took by hand last time, and how long it takes to edit each output to a sendable draft.
6. Decide with a threshold. Buy a platform only if it saves more hours than its monthly fee divided by your hourly rate, on the jobs you actually do every month.

A filled-in scorecard, with illustrative numbers

The numbers are invented to show how to read the table, not results from a study. In this pattern the assistant wins or ties on four jobs and the platform only clearly wins on the shortlist, saving 150 minutes on one job a month. If a consultant does that job for four clients a month, the saving is ten hours, which at $75 an hour is $750 against a $299 fee. If they do it for one client, it is $187.50 against $299, and the platform loses.

An appeal-letter test: prompt, output and fix

You are drafting an appeal for a small animal rescue charity.
Use ONLY the facts in the fact sheet below. If a claim would need a
number that is not in the sheet, write [NEED FACT] instead.
Audience: donors who gave once last year. Length: 220 words.
One story, one ask ($40 covers a vet check), one deadline (31 March).
Fact sheet: [paste approved facts]

A typical output, labelled illustrative: "Last winter, Biscuit arrived with a swollen paw and no name. Because of donors like you, he left in six weeks with a family. This year we expect to rescue [NEED FACT] animals, and $40 covers a vet check for one of them. Give before 31 March." Notice what is working. The flag stopped the made-up total. What you would fix is the line "Because of donors like you", which is generic and links the donor to a story they did not fund; replace it with the fact sheet's real detail. Run the same prompt without the [NEED FACT] rule and the letter usually acquires a confident statistic from nowhere.

A thank-you letter, before and after

Thank-you letters are the quietest win for an assistant, because the facts are few and the tone matters most. A before, as it often arrives from a rushed template: "Dear [first name], thank you for your generous gift of $[amount]. Your support makes a real difference." An after, from a prompt that supplied the gift date, the fund the money went to and one detail from the programme team: "Dear [first name], your $[amount] on 14 March went into the winter vet-care fund. Last week it paid for the dental work that let a shy collie called Mabel go to her new home. Thank you for being part of that." The second version has three specifics and one sentence of warmth. The edit that remains is yours: confirm the programme detail is true and that the donor consented to being named, if you name them anywhere.

Grant drafting: an assistant with a library, or Grantable and Apply

For grant sections, the assistant's quality depends on what you give it. Build a "proposal library" in a project: five past proposals that won, your standard organisational descriptions, budgets with narrative, and a list of approved outcome figures. With that, Claude or ChatGPT will draft a section in your client's voice that needs editing rather than rewriting. The same library can sit in Grantable, which is built around it; the difference is workflow, such as scans and dashboards, and capacity, not a different class of writer.

A before and after. Before: a consultant starts each section from a blank page and a pile of old PDFs, 6 hours for a needs statement and outcomes section. After: the project already holds the client's last two proposals and an outcomes sheet; the assistant produces a draft in two minutes; she spends about 4 hours checking every figure against the sheet, tightening the voice and adding what is new this year. The saving is real but smaller than the demo suggests, because checking cannot be skipped.

Funder research: where a database can pay back

Funder research is the clearest case for a paid platform, because it depends on data that changes weekly. Instrumentl Discover is $299 a month on annual billing ($349 monthly) for up to 3 users. The break-even sum is simple: divide the fee by your hourly rate. At $75 an hour, $299 is about four hours a month. If research for four clients currently takes you 6 hours each by hand and a database brings that to 3, you save 12 hours, three times the break-even point.

Two cautions. First, a database tells you who might fund a client; it does not tell you whether they would, so every shortlist still needs a read of the funder's guidelines. Second, annual billing saves roughly 14 per cent on Discover ($299 against $349) but commits you for a year. Use the monthly plan for the first quarter, and only move to annual billing when the hours log says the tool is earning its place.

Client-side platforms: Givebutter and Funraise

Many consultants advise on a client's donation platform rather than buying one. Two have clear AI offers worth knowing.

• Givebutter has a free tier with a free CRM and a paid Givebutter Plus plan from $29 a month, priced by contact count. Its pricing page lists a built-in AI feature called Givebutter Magic, for campaigns, goals and donor insights, and AI connectors that link its data to ChatGPT, Claude and other AI tools. Which plan includes which feature is not obvious from the page, so ask before you promise a client anything.
• Funraise describes a free, fee-based platform for organisations raising under $1 million a year. Its AppealAI tool, which writes appeal emails, social posts and website copy, is described on its page as free to use, and the same page advises against entering raw, unanonymised data into any AI tool. That is a sound rule for a consultant too.

The consultant's role is to match the tool to the client's size, and to say plainly that built-in AI in a donor system is convenient because the records are already there, which is also the reason to check where the data goes.

Keeping client and donor data safe in the trial

A realistic mistake. A consultant exports a client's last-year donor list, 600 rows with names, emails, postcodes and gift amounts, and pastes it into a personal ChatGPT account to find lapsed donors. The analysis is useful. The data has left the client's control, on a personal plan whose training setting the consultant never checked, and the client's written agreement never covered it.

The safe version has five steps.

1. Get the client's written agreement to the tool and the task.
2. Replace names with IDs (D001, D002), delete emails and addresses, and keep gifts in bands (under $50, $50 to $249, $250 and over).
3. Use a business plan, which does not train on business content by default, or switch off the training setting on an individual plan and describe the setting generically to the client.
4. Keep the key that maps IDs to names in the client's system, not in the chat.
5. Delete the chat when the task ends, and note the date in your engagement record.

The wider risks, including deepfakes and donor trust, are covered in charity AI risks: data protection, deepfakes and donor trust. For anything involving regulated personal data, ask a qualified adviser about your obligations as the party handling it.

Questions to put to a platform before you pay

A demo shows the best case. These questions bring out the rest, and a vendor that answers them plainly in writing is easier to trust than one that does not.

• Where does the funder or donor data come from, and how often is it refreshed? Stale deadlines are the commonest way a database wastes your time.
• Does my content train a model? Ask for the answer in the terms, not on a call, and ask whether it covers the AI features specifically.
• Can I export everything, including past drafts, if I cancel? A proposal library is an asset. Losing it on cancellation is a hidden cost.
• What happens at the usage limit? Grantable's plans differ by capacity, from 5 chat messages a day on Free to 200 on Pro, so a busy week can hit a wall.
• How many users, and may clients log in? Seat limits such as Instrumentl's 3, 5 or 15 users decide whether your whole team fits, and whether a client can see a shortlist.
• What is the price after the first year? Promotions are common, and the number to budget is the list price.
• Which AI features need a higher plan? On several pricing pages the AI feature sits on one tier only, and the cheaper tier lists none.

Put the answers in the same scorecard as your trial results, so the decision is made on the evidence in one place.

Which route for a solo, a trio or a team of eight

Solo consultant, three to five clients. One individual assistant plan at $17 to $20, plus Grantable's Free or Starter plan if grant writing is half your work. Revisit Instrumentl only if you can name a client for whom funder research is a monthly job.

Three consultants, ten clients. A two-to-three seat business plan on one assistant ($40 to $60 a month on annual terms, $50 to $75 monthly), shared project libraries per client, and one Instrumentl seat among the three. The $299 is about $30 a client a month, small against a retainer, and shared research saves repeated work.

Eight consultants. Business seats for everyone who writes, a shared library, Instrumentl Pre-Award ($499 a month on annual billing, up to 5 users) if grant work is the core of the practice, or Full Lifecycle ($999 a month on annual billing, up to 15 users) if more than five people research funders, and a written AI policy covering data. A written test, like the one above, should come before the second year's renewal.

Questions fundraising consultants ask before paying for a platform

Can I put donor names into ChatGPT or Claude?

Avoid it on personal accounts. Replace names with IDs, remove emails and keep gifts in bands before pasting. If you need real records in the tool, use a business plan, which does not train on business content by default, and get the client's written agreement first.

Does my client's nonprofit discount apply to my consultancy?

Probably not. OpenAI and Anthropic list nonprofit pricing for eligible nonprofit organisations, such as $8 a seat for ChatGPT Business Standard on annual terms. A for-profit consultancy should check eligibility with each vendor and assume it pays list price.

Is Instrumentl worth $299 a month for a solo consultant?

Only if funder research eats at least four hours of your month across clients at your hourly rate, since $299 divided by a $75 rate is four hours. Run a trial on two live clients and log the hours before you commit to annual billing.

Can an assistant write a whole grant application?

It can write a usable first draft from your past proposals, budget and programme facts. It cannot know your client's outcomes or the funder's current priorities, so every number, deadline and eligibility rule needs a human check against the funder's own page.

Which is better for appeals, ChatGPT or Claude?

Test both on the same three briefs and score them blind. Their prices are close, and the better writer for your voice varies by consultant. A ten-minute blind test beats any general ranking.
